15/10 = 18-x/x is the ratio of the larger to the smaller triangle
Cross multiply:
15x = 10(18 - x)
15x = 180 - 10x
25x = 180
x = 7.2
Plug back in to check
15/10 = 1.5
18-7.2/7.2 = 10.8/7.2 = 1.5 :)
Answer:
a. 60 centimeters
b. 67 centimeters
Step-by-step explanation:
a.
12 × 4 = 48
(6 × 4) ÷ 2 = 12
48 + 12 = 60
b.
7 × 10 = 70
(2 × 3) ÷ 2 = 3
70 - 3 = 67
X = fraction 1 over 12
x = fraction 1 over 3
x = 3
x = 12
The given choices are the successive steps to solve the question :fraction 1 over 6x = 2
of which the last choice is the solution.
The equation in the question is not the same as the one in the picture so here's the answers to both of them.
Q1 - 1/3 or 0.333333
Q2 - 1/108 or 0.009259
